Bio-th5 Ply Protective Face Masks, 5 Layers Double Melt-Blown Breathable and Comfortable Elastic Ear Loop with 3D Ear Rings Light Weight Pack of 20 PCS

In the photo the brand and packaging is bio-th and the print in the mask is white. But the one arrives is with black print KINGFA GB 2626-2006. The fit is not also good.

Wasted my money as the masks are too small to comfortably use them. I’ll have to give it to somebody with kids… maybe they’ll fit them.

Very comfortable and easy to use

While there is a newer PRC Certification Standard for KN-95 masks.... GB-2626-2006 remains an approved certification standard (endorsed by FDA, whether specific masks have been certified by NIOSH or not).These masks conform to GB-2626-2006. (yes.. there is a QA certification included inside the plastic package)Form and fit are identical to medical grade KN-95s sent to me by family from China. So... even though these are not specifically approved KN-95 for medical grade use... these are fine, are not counterfeits, and honestly the general public does not need medical grade (ie: sterile production and packaging for use by medical facilities).Quality of these masks is top notch. The common weak point in both surgical and KN-95/KN-100 masks from China is the earloop welds to the mask. It is easy to fix a broken weld with a small hot glue gun... but it's nice to not have to rehab a defective weld. These masks have very robust machine ultrasonic welds at the ear loop attach points.The mask adjusts easily, and the metal band at the nose position is robust, yet easy to adjust.Breathing is easy and relaxed in this particular mask.Given the excellent pricing of a 20 pack here... I think I will immediately order a back up pack just in case these are no longer for sale when I finish with this first pack.These masks are dimensionally identical to every other KN-95 style mask I have sourced from China (this will be my 5th different branded mask from China. NO COMPLAINTS.

Update on masks:I have worn several of these masks since my last review... the nose part still does not fit, but without the clip, they are very comfortable... I adjust the ear loops by tying a knot in it...Love the wide ear loops, the breathing space, and the fact that they are separated by 5 to a pack...may buy again....Previous ReviewFinally found a mask that fits the size of my face... these masks are very smallPros:1. Quick delivery2. Size fits my face3. Soft4. Due to size, may be a better fit for females and children / people with small faces5. Like the duality of wear (with or without the closure)Cons:1. Unable to get the nose bridge wire to adjust..... could not get it to remain stable or adjust for my face..the mask would get very loose, allowing vision blockage, or constant movement on my face....2. Appears to fit small faces only3. Due to nose bridge problems - felt unsafe - fit was not snug for me4. Mask odor (not unusually strong, but there)5. PriceyAppears to be a quality mask; however, I do not plan to purchase these again... spent tooo much time trying to get it to fit correctly... due to nose bridge problems, it was either too large or too small

Had to get on a plane and was unable to locate N95 masks, so took a chance on these. No these are not N95s, but they are far superior to surgical masks and cloth masks. They do get a little warm, but they have plenty of room inside, so you don't ever get any material in your mouth when trying to talk. Only minus was my husband tried to use the connector behind his head instead of using them as ear loops, and one of the loops broke the 1st time he removed it- just too small to use with his head size. We have now used several of them for several days, looping them behind our ears. None of the others have broken. Highly recommend!
